Brunswick Bowling Ball Cores

Every Brunswick core in a ball we sell, with its RG, differential and mass bias, on one map

Brunswick puts 12 different cores into the 31 Brunswick balls we have in stock today: 7 symmetric and 5 asymmetric. The newest is the Brunswick Fury Core (the Fury line). The strongest flare comes from the Brunswick Portal X Core (differential 0.054), and the earliest-revving is the Brunswick Alert Core (RG 2.470). Every core below links to its own page with specs by weight and the balls built on it.

Questions bowlers ask

What cores does Brunswick use in its bowling balls?

12 different cores are in the Brunswick balls we stock today: Light Bulb Core, Fury Core, Rampart Core, Tiered Hexagon Core, Alert Core, Danger Zone Core, Dual Centric Core, Infinity Core and others. 7 are symmetric and 5 asymmetric. Each core’s page lists its RG, differential and mass bias by weight.

Which Brunswick core has the most flare?

The Brunswick Portal X Core, with a differential of 0.054 at 15 lb, the highest of Brunswick’s current cores. Higher differential means more flare potential and a stronger, more angular motion.

Which Brunswick core revs up earliest?

The Brunswick Alert Core, with an RG of 2.470 at 15 lb, the lowest of Brunswick’s current cores. A low RG core starts revving sooner and reads the midlane earlier.

Are Brunswick cores symmetric or asymmetric?

Both. Of the 12 Brunswick cores in stock, 7 are symmetric (one pin marker, a smooth continuous arc) and 5 are asymmetric (pin and PSA markers, a stronger and more angular backend).

What is Brunswick’s newest core?

The Brunswick Fury Core, in the Fury line, first sold here in June 2026. It is symmetric with an RG of 2.524 and a differential of 0.038 at 15 lb.
